isVoid

Returns true if the interval is void.

isDegenerate

Returns true if the interval is degenerate.

getStart

Returns the start of the interval.

getEnd

Returns the end of the interval.

count

Returns the number of elements in the interval.

contains

Methods

HxInterval.isVoid(val)

Returns true if the interval is void. A void interval is an empty interval with no valid start or end bounds.

Returns:

True if the interval is void.

Return type:

bool

HxInterval.isDegenerate()

Returns true if the interval is degenerate. A degenerate interval is an interval with equal start and end bounds. It does not contain any element.

Returns:

True if the interval is degenerate.

Return type:

bool

HxInterval.getStart()

Returns the start of the interval. Cannot be called on a void interval as it does not have a valid start.

Returns:

Start of the interval.

Return type:

int

HxInterval.getEnd(value)

Returns the end of the interval. Cannot be called on a void interval as it does not have a valid end.

Returns:

End of the interval.

Return type:

int

HxInterval.count(value)

Returns the number of elements in the interval. A void or degenerate interval does not contain any element.

Returns:

Number of elements in the interval.

Return type:

int

HxInterval.contains(value)

Returns true if the interval contains the given value, false otherwise.

Parameters:

value – element whose presence in this interval is to be tested.

Returns:

True if the interval contains the value.

Return type:

bool

HxInterval.toString(value)

Returns a string representation of the interval.

Returns:

String representation.

Return type:

string
